DEWALT Diamond Cup Grinding Wheel, 4-Inch (DW4772T): Ultimate Precision and Long-Lasting Performance Review

This thing really works! It is very aggressive and quickly abrades masonry. I tried to keep the angle grinder as level as possible so the wear on the pads was even, but they held up pretty well. This kicks up a lot of dust. So if you can get the area wet and keep it moist, the dust will be greatly reduced (and probably extend the life of the wheel). Just be careful with water near the power tool. The only thing I would like to change is that the pads don't go back as far because they would be…

This tool grinds cement very quickly and levels concrete in minutes depending on the size of your project. and you have to make them move in all directions to make it nice and smooth and flat. After that you need to reseal your concrete. You will be really surprised at how much is created with the first use. That shouldn't be a problem, but it really seems to surprise you every time you use it. You can use it wet with plenty of water, or better yet, use a good vacuum with a vacuum attachment. I

Excellent grinding disc for leveling cement. Don't use it on a weak angle grinder.

I leveled the pads on the forty-year-old concrete to secure the posts for the platform…

After sending back the Temo brand mug because it was a piece of junk - poorly balanced and took less than two minutes to make - I order a Dewalt. It is excellent!

UPDATE: I've been using it for 5-6 weeks and I'm still impressed. After at least 50+ hours of hard rock grinding there is still a lot of…

I bought the exact same diamond grinding cup from a local wholesaler (Lowes) in January. I used it to sand a 13ft x 15ft concrete floor in preparation for a penetration sealer. I've also used it to remove a pile of self-leveling and conventional concrete from a pool deck, as well as removing an old thin layer from a 3' x 8' knee wall. The wheel I used for all these things got pretty low so I decided to order another one here quickly so I don't have to go to the store and waste time. When this…
